Parallel Port: Can status bits be used as outputs?

I know a lot of people want to use parallel port outputs as inputs; I
have the opposite dilemma.

I am working on a particular application where it would be far more
convenient to use pins 10-13 on the parallel port (normally status
bits) as outputs. Otherwise I would have to create custom cabling
which would be rather inconvenient.

Is it possible to use pins 10-13 as outputs on most PC parallel ports?
Could doing so damage the card or PC?

I tried briefly to do this without much luck. I believe it is possible
but you need to use a the parallel port subsystem. My quick solution
was to use two 373 latches and the eight data bits of the parallel
port. Using one of the bits as chip select, I was able to get 14 I/O
pins.
